As a new participant in the Board a little background-I'm 76, got diagnosed with PD five years ago altho I think it all started about five year before.My worst symptom is freezing while walking with loss of stability - irrecoverable- and a crash , so far without killing myself. I have almost all of the other symptoms of PD except tremor . That's about it.I'd like to thank Bruce and Googy for their responses to my earlier post. Walt
